"For warm tones, dilute 1 part stock solution with 3 parts water and develop prints 2.5 to 3 minutes at 68°F. For very warm tones and more open shadows, especially with Cykora, dilute 1 part stock solution with 6 parts water, giving prints 3 to 4 times normal exposure and 2.5 to 5 minutes development."

"The prepared stock solution is clear but slightly colored. The color in this case does not indicate the developer has deteriorated or is unfit for use. For use, dilute 1 part stock solution with 1 part water."

Suggested : use at 65° to 70°F.
for bromide paper - dilute 1 part stock to 6 parts water
for chloro-bromide paper - dilute 1 part stock to 4,5, or 6 parts water
for chloride paper - dilute 1 part stock to 3 parts water
"After solution is completely dissolved, filter and store in amber colored, tightly stopped bottles."

"Add bromide as needed. Dilute the developer for softer effects."
"Since Amidol does not keep well, it may perhaps be better to add the amidol at the time of development as it quickly dissolves. Potassium metabisulphite may be omitted in that case. Citric acid may be used as a preservative instead of the potassium metabisulphite."

"Burki and Jenny reported that tones varying from brown to red-chalk may be obtained with chlorobromide papers by direct development in a catechol developer in connection with ammonium sulfate. The solutions are as followsabove)
For red-brown tones take equal parts of A and B. For colder brown tones decrease B and for redder tones increase B. Expose so that the desired density is obtained in 2.5 min. @18°C.

"Howell has reported a procedure for obtaining pleasing brown-black tones from almost all types of papers by bleaching the black-and-white print and redeveloping in a sulfite-free catechol formula. The method has the advantage that the beautiful tones of catechol development may be achieved without its disadvantages. One may use his favorite reliable MQ formula such as D-72, D-52, ect., to obtain a normal black-and-white print. After fixing and washing thoroughly, bleach the print in a ferricyanide formula just as for sulfide toning.

Immerse print in this bleach until the deepest blacks have gone to a faint brown. Wash 5 min. in running water and redevelop.

This bath does not keep well and must be used immediately after making up. It will not safely develop more than two 14X17 prints. The bleaching bath may be used until exhausted. During redevelopment the print passes through various unpleasant shades of reds and browns, and development is complete when the tone has changed to a brown-black with no further change. Wash for 1 hour and dry as usual. A slight degree of intensification takes place, but this need not be allowed for in making the black-and-white print, as it gives an additional pleasing richness to the blacks."

This is really great stuff. May I make a suggestion - can this be made part of the static content at lfphoto.info? That way, folks will not have to use the search terms and it will be more readily available. Cheers, DJ

I am a long time user of several of the Agfa formulas, but have always seen them published as Ansco (or GAF) formulas. This post shows that they were developed by Agfa before the Agfa/Ansco merger in 1928.

I'll have to check this (tomorrow, when I get home), but I thing the "AGFA 130" formula here is the Ansco 130 one. AGFA 130 is a completely different developer (without Glycin) - but I have the AGFA recipe collection at home and will check.

Old Formulas: Paper

Ole, that is what I noticed too. Agfa must have brought the 130 glycin formula (and many others) to the Agfa/Ansco merger in 1928, but then Ansco must have acquired the rights to publish the formulas when the companies were split up as a result of WWII. The formulas for 17, 17M, 20, 22, 30 X-ray, 40, 42, 45, 48M, 61, 64, 70, 72, 79, 81, 90, 103, 110, 113, 115, 120, 130, and 135 were published as Ansco formulas after the war.

Hi there,

Eric and Ole : you are probably correct, the booklet says Agfa on the front, copyright to GAF 1941 on the flyleaf and Agfa/Ansco on the rear. I guess these were changed to Ansco formulas after the war. I just entered what was there. Why would Agfa use the same numbers twice?

Old Formulas: Paper

Thanks Paul. I thought you were working with a pre-1928 publication. It could be, then, that Agfa had a developer 130 and Ansco also had a developer 130 when they merged in 1928. Agfa Ansco became part of General Aniline & Film (GAF) in 1939.

Regarding the Agfa 120 developer. This is a completely different version from the one listed in "the Darkroom Cookbook" as Agfa 120 Brown-Tone Paper Developer. What is the story? Is this really an Ansco formula, or is the one in the book an Ansco formula?
